The set_default_stage() method of StageManager should not be used
by application code; technically, nothing in Clutter uses it, and
StageManager's API is not considered public anyway.
The IN_DESTRUCTION flag is set around the unrealization and disposal of
the actor in clutter_actor_destroy() but is never unset (it's set twice
instead).

It makes more sense because the grave key is close
to the tab and escape keys which the other cycle
keybindings use.
This always works better for gnome-shell, which
switchings between applications by default with alt-tab.
The user can now alt-tab to the application they want,
and then move their finger to the grave key to select
the window they want.
When we focus a window on a different desktop, and the calc_showing
idle that hides/shows the windows gets run before we get focus events
back from X, we think that we are hiding the window with the focus
so we focus a "random" window to avoid leaving the user with no focus.
Work around this temporarily by checking display->expected_focus_window;
this isn't a perfect fix because there are cases where
display->expected_focus_window corresponds to a window we tried to
focus in the past but failed, but it makes things work fairly well.

Currently, setting the :text property has the side-effect of
setting the :use-markup property to FALSE. This prevents
constructing a Text actor, or setting its properties, like:
g_object_set (text,
"use-markup", TRUE,
"text", some_string,
NULL);
as the ordering becomes important. Unfortunately, the ordering
of the properties cannot be enforced with ClutterScript or
with language bindings.
The documentation of the clutter_text_set_text() method should
be expanded to properly specify that the set_text() method will
change the :use-markup property to FALSE as a side effect.
Transform functions allow the use of g_value_transform() to cast
GValues. It's very handy to have casts to and from G_TYPE_STRING as it
allows generic serialization and parsing of GTypes.

Current parsing of units has a number of shortcomings:
* a number followed by trailing space (without any unit specified) was
not recognized,
* "5 emeralds" was parsed as 5em,
* the way we parse the digits after the separator makes us lose
precision for no good reason (5.0 is parsed as 5.00010014...f which
makes g_assert_cmpfloat() fail)
Let's define a stricter grammar we can recognize and try to do so. The
description is in EBNF form, removing the optional <> which is a pain
when having to write DocBook, and using '' for the terminal symbols.
Last step, add more ClutterUnits unit test to get a better coverage of
the grammar we want to parse.

Parse #rgb and #rrggbb in addition to forms with the alpha channel
specified. This allows conversion of colour strings from documents such as
CSS where the alpha channel is not specified when using '#' notation.
This patch also adds the relevant conformance test.

gdk is an optional clutter dependency, so the pick buffer debugging option
needs some guards so we don't break, for example, the OSX builds. This also
adds a comment for the bit fiddling done on the pick colors used to ensure
the pick colors are more distinguished while debugging. (we swap the
nibbles of each color component so that pick buffers don't just look black.)
ClutterGroup previously calculated the size as the distance from the
left edge of the leftmost child to the right edge of the rightmost
child except if there were any chidren left of the origin then the
left edge would be zero.
However the group is always allocated its size relative to its
origin so if all of the children are to the right of the origin then
the preferred size would not be large enough to reach the rightmost
child.

Since the Great Rework of ClutterUnits, functions have been using
'units' not 'unit' in their name. clutter_value_get_unit() is a left
over from a dark age, its declaration and documentation have been
updated but not the symbol itself.
Instead of having an assertion failure with a message of dubious
usefulness, we should probably use a more verbose warning explaining
what is the problem and what might be the cause.
The user-initiated resize is conflicting with the allocated size. This
happens because we change the size of the stage's X Window behind the
back of the size allocation machinery.
Instead, we should change the size of the actor whenever we receive a
ConfigureNotify event to reflect the new size of the actor.
We force the redraw before mapping, in the hope that when a composited
window manager maps the window it will have its contents ready; that is
not going to work: the solution for this problem requires the implementation
of a protocol for compositors, and not a hack.
Moreover, painting before mapping will cause a paint with the wrong
GL viewport size, which is the wrong thing to do on GLX.
When we create the timeline dummy timeline to ensure that our later
functions that should be run during repaint get called called, pass in
G_MAXUINT to make the duration very long, not 0. (It will get reset
whenever there is no repaint later to run, so the fact that G_MAXUINT
is only ~40 days isn't a problem.)
This fixes a warning from Clutter, but also a real problem.
There was a problem where if, for example, a restack was triggered
out of a clutter event handler, then after Clutter processed the
events, it would proceed immmediately on to repaint the stage without
ever returning control to the GLib main loop. So even though we
had an idle handler installed with a higher priority than the
Clutter stage repainting the clutter stage repainting would happen
first and we'd get a wrong frame.
Fix this by introducing the idea of "later functions", which abstract
the idea of "doing something later" away from g_idle_add() and use
a combination of GLib idle functions and Clutter "repaint functions"
to get our callbacks triggered at the right time, even when they
are installed from a clutter event handler.

This also resolve a FIXME where MUTTER_PRIORITY_BEFORE_REDRAW
could starve stage repainting.
gnome-shell is no longer using MetaAltTabHandler, so there's no need
to keep that abstraction around.
This reverts commit 1d5117a6 (and a comment from 7b0ba87b), with a bit
of rebasing and whitespace cleanup.

The chapter on how to subclass ClutterActor inside the API reference for
Clutter is still using ClutterUnit and referencing to concepts that have
been changed since the document was written.
The return value of XGrabKeyboard() wasn't actually being assigned
to the 'result' variable so we didn't notice when grabbing the
keyboard failed.

When not building a debug build the compiler was warning about empty
else clauses with no braces due to code like:
if (blah)
do_foo();
else
COGL_NOTE (DRAW, "a-wibble");
This simply ensures that even for non debug builds COGL_NOTE will expand to
a single statement.
